In the theme folder you can find the LESS variables in the following files:

/assets/less/variables.less (Twitter Bootstrap variables)

/assets/less/{theme-name}-variables.less (where {theme-name} is the current theme name like schema-corporate)

You can edit these files directly or (which is better if you want to get automatic updates): you can edit the variables directly on the themes options page. Just activate custom colours and scroll down to the “LESS Variable Changer”.
